[Secure-testing-team] Bug#637477: possibly allows shell injection

Hi,

shared/inc/sql/lists.php includes code like

  if ($_REQUEST[$tunable_name]!=""){
          //i write in the file
          $write_line = "echo ".$_REQUEST[$tunable_name]." > ".$option_file;
          exec($write_line);
  }else{ //i remove the file

and does not seem to check the contents of $_REQUEST for sanity as far as I can
see.

(I did not try actually using it as I do not have dtc setup.)

Regards,
Ansgar
